missed shot??

hey one of my buds missed a shot he takes them tuesday and friday he missed this fridays shot and i was wondering if he just got back on track this tuesday again would that really matter would he be aight or what thanks for any help??

what is he shooting? the half life of some esters are very short. here is the formula for how much is in your system. It's not perfect but it will give you a good idea:
(mg per shot)*2^((-time since last shot) / (half life))
as an example:
test propionate half life = 2 days
if you were shooting a 100mg/ml shot after the third day in your system you would have:
100*2^(-3/2) = 35mg's
